We didn't pass a script ID with the code creation events for profiling. This made DevTools lose the connection to the wasm script, hence jumping from the profiler entry to the source did not work. This CL changes the timing of code logging a bit such that the script is always allocated before logging. In the queue of code to be logged we then also store the script ID, and finally set it on the {CodeEntry} object.

Although every Primitive is a Data, the Cast operations for the subclasses of Primitive do not allow casting directly from Data to the subclasses without first going through Value. Because of this, Primitives extracted from a V8::FixedArray require two casts to get to the "real" type. Thus, as a convenience to embedders, this change makes it possible to cast directly from Data to all the subtypes of Primitive. Also, this change makes the parameter names in the declarations match those in the definitions, though there does not seem to be a universally followed convention regarding these.

Import wrappers were only logged if logging was enabled during compilation. If the profiler is enabled later, and regular wasm code is logged via {NativeModule::LogWasmCodes}, the import wrappers were missing. This CL fixes the long-standing TODO, and adds tests which triggered that code path. Those tests were hanging before because the expected functions did never appear in the profile. Drive-by: If {WasmEngine::LogOutstandingCodesForIsolate} detects that code logging is disabled by now, it should still clear the {code_to_log} vector.

For logging existing functions, currently walk the heap four times: 1) For getting the number of JS Code objects, 2) for getting the actual JS Code objects, 3) for getting the number of wasm code objects, 4) for getting the actual wasm code objects. This CL refactors this to do only two heap walks (one for JS, one for wasm). It also avoids the use of the brittle {ScopedVector} and uses a {std::vector} instead.

Previously V8 would wrap the WebAssembly.Memory backing stores into Uint8Arrays and report that as memories, but that's confusing to the developer, since that's not what's really being used. The way that DevTools presents the backing stores of memories, it's still perfectly possible to get hold of an Uint8Array if that's what the developer is looking for. To make it possible to easily identify the WebAssembly.Memory objects in the DevTools front-end (in particular for the memory inspector) we add a 'webassemblymemory' subtype to the Chrome DevTools Protocol. We also improve the description for the memories to include the number of active pages.

Dependent code deopts were only printed with --trace-deopt-verbose earlier. These just print one line and are helpful with --trace-deopt. If we don't print these with --trace-deopt, it appears as if we are optimizing without any deopts in between which is a bit confusing.

VerifyNewSpaceTop() assumes that original_top_ and allocation_info_.start() always match. PublishPendingAllocations() violates this invariant by only updating original_top_ in the NewSpace. Fix this by using MarkLabStartInitialized() for NewSpace. Alternatively we could loosen the DCHECK in VerifyNewSpaceTop(). The fix doesn't matter too much since Ulan's LAB refactoring will get rid of that code anyways.
